Nautilus is very slow
One month ago I updated (no fresh install) to 12.04.
Since then nautilus got extremely slow. When I open a folder that contains many subfolders I sometimes have to wait 4 seconds until everything is displayed. This has never been like that before, in previous versions I could always browse between my files extremely fast.
If I start nautilus with root-rights from a terminal, it does work perfectly.
I looked in "additional drivers" and changed from Nvidia current-version-update to the recommended drivers. This drastically increased the performance and speed of file browsing, unfortunately just for a couple of days. Now I am stuck again with the very slow Nautilus.
I also tried to install the latest nvidia driver like it was suggested here: http://www.techlw.com/2012/03/install-nvidia-drivers-on-ubuntu-1204.html Did not work at all.
Also when using the dash to try to find files it does not respond properly: does not find files or loads for ages until the file is displayed.
I am working on an Acer Notebook with
Intel® Core™ i5 CPU M 430 @ 2.27GHz × 4
6GB RAM
GeForce GT 320M/PCIe/SSE2
64 Bit Ubuntu 12.04
I figured out some ways to speed up nautilus: bookmarks and previews. But it's still not as fast as it should be ... and I have an SSD!
Bookmarks:
To fix it delete all your bookmarks, restart and then add back the ones you can't live without.
Using strace I realised that nautilus was stating lots of files for every view. Even files that were not in directory I was browsing during the trace. I think nautilus is trying to pre-cache these bookmarks.
I had one network drive as a bookmark ... this might have been the reason why nautilus was taking several seconds to load.
Preview settings:
Disable the previews in the preferences as follows:
I do not know if it is any help. But I removed the following plugins: nautilus-sendto, nautilus-sendto-empathy, nautilus-share, nautilus-open-terminal. Now Nautilus seems to be working quite fast.
in your post you mention a murrine critical error surely this is the fault of some theme,which would explain why rooted nautilus works ok as root doesn't carry the user theme,try changing to default theme and test.
This is most definitely an issue with Nautilus itself. Here is a bug report on launchpad:
